A critical point of a function y = f(x) is a point (c, f(c)) on the graph of f(x) at which either the derivative is 0 (or) the derivative is not defined. Let us see how to find the critical points of a function by its definition and from a graph.
But now that we’ve turned the left side of our equation into a perfect square, all we have to do is factor like normal. Completed quadratic formula: x2+6x+9=7 Factor left side of the equation: (x+3)2=7 Take the square root: (x+3)2=7 Subtract 3: x=±7−3 Final solutions...
